[SOLVED] RTT viewer multiple windows

It looks like system (laptop windows 7) is not supporting more than two windows of RTT viewer simultaneously. When I connect, third one, it disconnects, one of the two's.
Is there any way to connect four windows of RTT viewer simultaneously as in my case, there are four BLE devices who wants to communicate with each other and I need debugging?

Sorry for the delay in response.
RTT only works over one RTT viewer simultaneously per J-Link. If you use more than one they will start "stealing" data from each other and none of the RTT Viewers will have a full data set.
So you need 4 J-Link devices to show 4 RTT Viewers for 4 target devices.

Best regards,
